You have a simple pendulum that's 1.4m long and has a 100g mass at the end. In Lewis Hall, what is the period of the pendulum? You then take this pendulum to the moon and measure the period again. What is the new period? Moon gravity is one sixth of earth's.
Two speakers face each other and radiate coherently and in phase. How many loud maximum intensity positions are there between the speakers
A 39.0-kg child swings in a swing supported by two chains, each 3.10 m long, Find the force exerted by the seat on the child at the lowest point
A 5.00 m long uniform ladder leans against a smooth wall and its base rests on a rough floor. The ladder has a mass of 18.0 kg and its base is a distance of 2.30 m from the wall. A person of mass 80.0 kg climbs 2.50 m up the ladder. If the ladder ..
You have been visiting a distant planet. Your measurements have determined that the planet's mass is two times that of earth but the free-fall acceleration at the surface is only one-fourth as large. What is the planet's radius
Determine the amount of energy the reaction releases. Be sure to take into account the mass of the electrons associated with the neutral atoms.
